Take the other number as x and find the value of x
Hope u have
A GREAT DAY!!

Answer 2

Answer:

Given :-

• The sum of two integers is 50.
• One of the integers is - 30.

To Find :-

• What is the other integers.

Solution :-

Let,

$\mapsto \: \sf Other\: Integers =\: x$

Given :

• Sum of two integers = 50
• One of the integers = - 30

According to the question by using the formula we get,

$\footnotesize \bigstar \: \: \sf\boxed{\bold{\pink{Sum\: of\: two\: integers =\: One\: of\: Integer + Other\: Integer}}}\: \: \: \bigstar$

By putting the above values we get,

$\implies \sf x + (- 30) =\: 50$

$\implies \sf x - 30 =\: 50$

$\implies \sf x =\: 50 + 30$

$\implies \sf\bold{\red{x =\: 80}}$

$\therefore$ The other integers is 80 .

VERIFICATION :-

$\leadsto \bf x + (- 30) =\: 50$

By putting x = 80 we get,

$\leadsto \sf 80 + (- 30) =\: 50$

$\leadsto \sf 80 - 30 =\: 50$

$\leadsto \sf\bold{\purple{50 =\: 50}}$

$\longrightarrow \bf L.H.S =\: R.H.S$

Hence Proved !
